Quantum Big Bang Cosmology: Complex Space-time General ...
In this section see how Hubble's Law emerges in the generalized model.
Hubble's law is one of the cornerstones of modern cosmology. While one might
think a scale factor that depended on the radius coordinate might not be
consistent with ...

Introduction to Cosmology
Hubble's fundamental discovery was that the velocities of the distant galaxies he
had studied increased linearly with distance: v = H0r. (1.12) This is called
Hubble's law and H 0 is called the Hubble parameter. For the relatively nearby
spiral ...

The Physical Universe: An Introduction to Astronomy
The data points are well-fit by a straight line that demonstrates the validity of
Hubble's law: v oc r. The numerical value for Hubble's constant H0 can be
obtained from this diagram as outlined in the text. accurately, the redshift)
measurements ...

Astronomy: A Physical Perspective
This is the same as Hubble's law, if we make the identification HO = I/to (18.4)
Then, 1/H0 , called the Hubble time, is the age of the universe if the expansion
has been constant. Actually, as we will discuss in Chapter 20, the expansion is
not ...

Cosmology: A First Course
expressed in Hubble's law, v = H0D, which connects the recessional velocity, v,
with the distance, D, of the galaxy. The Hubble parameter*, or Hubble constant,
Ho, measures the rate of expansion of the universe. Its value is hotly debated by
...

An Introduction to Galaxies and Cosmology
what is its corresponding value in SI units The origin of the scatter in the
relationship between redshift and distance is an important consideration when
using Hubble's law. What would be the effect on the plot of redshift against
distance if, ...

Provided that the redshift is due to the Doppler effect, the recession velocity v of a
galaxy is related to its distance r from us by Hubble's law, £ 104 = Hr 41-9 103
102 where H is the Hubble constant. In principle, the value of H is easy to obtain
...

New Understanding Physics for Advanced Level
364), Hubble proved that the speed is proportional to the distance. This is known
as Hubble's law. Speed of recession v = H X d where d = distance to the galaxy,
H = Hubble's constant. The accepted value of H is approximately 65 km s 1 Mpc ...

Evolution: A Scientific American Reader
Some people get confused by the fact that some galaxies do not obey Hubble's
law. Andromeda, our nearest large galactic neighbor, is actually moving toward
us, not away. Such exceptions arise because Hubble's law describes only the ...

Physics for Scientists and Engineers, Volume 5, Chapters 40-46
If the average density of the Universe is small compared with the critical density,
the expansion of the Universe described by Hubble's law proceeds with speeds
that are nearly constant over time. (a) Prove that in this case the age of the ...
